As a cleaning method, it is often used for priming a surface for the application of paint or a sealant. When painting, one doesn’t want to trap dust, dirt, or bubbles in a previous layer of paint, or other imperfections under the new layer. By launching small bits of abrasive at the surface at a high speed, all imperfections are knocked loose and can then be easily washed off, creating an incredibly smooth surface upon which to lay the new layer of paint.
Bead blasting is the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface.
It is used to clean calcium deposits from pool tiles or any other surfaces, and removes embedded fungus and brightens grout color. This process is notably used as an efficiently popular way to clean tile surfaces in swimming pools. It is also used in autobody work to remove paint.
